The three jaw universal chuck, as shown in Fig. Thus chuck is used for holding round and hexagonal work. It is used to hold hollow work pieces to machine their external surface.
Hello Readers, today in this paper we will discuss Lathe Machine's Accessories and Attachments, after complete reading this article you will understand the devices which are used in lathe machine, and able to differentiate between Lathe Accessories and Attachments. So let's get started. The Lathe Machine Accessories are those which are used for holding and supporting the work material or for holding the cutting tool.
Lathe is a machine tool which holds the work between two rigid and strong supports, called centers, or in a chuck or face plate. The cutting tool is rigidly held and supported in a tool post and is fed against the revolving work.
While the work revolves about its own axis, the tool is made to move either parallel to Cylindrical surface or at an angle with the axis Tapered surface to cut the desired material. Simplest of all types of lathe Contains Bed, Headstock, Tailstock, Tool post on adjustable slide No feed box, Lead screw, Carriage Headstock spindle speed to rpm Applications: Wood working, spinning, polishing etc. Types of Lathe 2. Engine or Center lathe Most widely used Early lathes were driven by steam engines and so the name engine lathe Heavy duty Head stock is much more robust in construction Contains additional mechanism for multiple speeds Carriage, Feed rod and Lead screw are available and hence, longitudinal and.
Tool room lathe Greater accuracy More versatility Wide range of speeds and feeds Applications: Precision work on tools, dies,. Used for special purposes Wheel lathe: For finishing journals, turning locomotive wheels Gap-bed lathe: A section of bed adjacent to tailstock is.
Automatic control: Once the tools are set and the machine starts, all the operations will be performed automatically.
Workpiece material Cutting tool material Type of operation Workpiece size Surface finish Cutting fluid Rigidity of machine tool. By belt drive on cone pulley fitted on the headstock spindle with or without a back gear arrangement.
In a belt driven back geared headstock, multiple speeds can be obtained 1. Direct speed or back gear out 2. Indirect speed or back gear in.
Cross feed facing, parting, etc. Angular feed taper turning, chamfering, etc. Tumbler gears are used to give the desired direction of movement to the lathe carriage, via lead screw or feed rod. Log in Get Started. If you can't read please download the document.

In this article, you will learn what are different Lathe Attachments and Accessories for lathe machine and also you can download the PDF file of this article at the end. A lathe is a machine that holds the workpiece on a chuck and tool on a toolpost, the lathe machine rotates the workpiece about an axis to perform different lathe operations such as turning, facing, chamfering, thread cutting, knurling, drilling and more with tools that are applied to the workpiece to design an object with symmetry about that axis.

The different types of centres are used for different types of workpieces and also for specific purposes. The important types of centres used as shown in the figure below. This is very important of all other centres and here the tip is made of hard material.
Home About Wiki Tools Contacts. In this operation, the workpiece is revolved in a chuck or a faceplate and the tools which are fitted to the tool post is fed into the work. In the case of a lathe, the taper on a given workpiece is obtained by tuning the job and feeding the tool at an angle to produce a gradual increase or decrease in the diameter of the workpiece. Using a die handle is a common method of external thread cutting on the lathe. The base of the compound rest is graduated in degrees. A trained Lathes can be divided into three types for easy identification:operator can accomplish more machining jobs with the engine lathes, turret lathes, and special purpose lathes.
